利用大豆和圆葱两种作物高矮不同、生理性状不同的特点,将两种作物搭配栽培,可以获得一地双收,提高产值的效果。选有灌溉条件的平肥地,施足农肥。3月中旬作宽1米的南北向畦。畦东部70厘米宽的部位覆盖地膜,西部作成20厘米宽小垄。3月下旬至4月上旬在覆膜部分栽圆葱,小行距12厘米,栽5行,亩保苗2.4万株。4月20日左右播大豆,穴距20—25厘米,每穴播3粒种子,种1行,出苗后留双株,亩保苗6000—8000株。7月10日左右收圆葱,然后用犁把畦面破开,将大豆培成大垄,既防旱保墒、通风透光,又可起到防止倒伏的作用。
Using the characteristics of different height and physiological traits of two crops, soybean and onion, the two crops can be cultivated in pairs to increase the output value. Select the flat conditions of irrigation, Shi enough fertilizer. Mid-March for the width of 1 meter north-south 畦.畦 70 cm wide east cover the plastic film, making the western ridge 20 cm wide ridge. Late March to early April planted in the film part of the onion, small row of 12 cm, planted 5 lines, 24,000 mu seedlings. April 20 about sowing, acupuncture points 20-25 cm, 3 seeds per hole sowing, a line, leave double strains after emergence, acres of seedlings 6000-8000. July 10 harvest onion, and then plow noodles open, soybeans into a big ridge, both drought and moisture, ventilation and light, but also play a role in preventing lodging.
